Abstract: 781,142. Iris diaphragms, photographic cameras. SCHNEIDER, M. C. Nov. 11, 1955 [Jan. 22, 1955], No. 32328/55. Classes 97(1) and 98(1) In a lens mount an iris diaphragm can either be set or pre-set to the required aperture by adjusting the position of a cam surface relatively to a fixed pivot carrying one diaphragm blade or nose extending from which, in the adjusted position of the blade (all other blades being simultaneously similarly adjusted), makes contact with the cam but may be held out of contact, the diaphragm being fully opened by means of an additional diaphragm ring carrying a deflecting member. As shown a pin h on the additionad diaphragm ring co-operates with a lug c<SP>1</SP> on nose c and removes the nose from contact with the cam surface b<SP>1</SP>. When the pin h is retracted, spring f returns the diaphragm to its initially set aperture. The return of the additional diaphragm ring may be effected, on its release from manual restraint, by a further spring. The diaphragm scale may extend half way round the lens mount and the scale markings corresponding to the values of relative apertures usually indicated on photographic cameras, may be equi-distant. The form of diaphragm control disclosed is more particularly applicable to single lens reflex cameras. The angular travel of the additional diaphragm operating ring may be as small as 30 degrees.
Patent GB-630319-A (GB)
Title: Improvements in or relating to compositions containing polymeric silicones
Filed: 1946-11-04
Abstract: An organo-silicon oxide polymer is stabilized against deterioration when heated in an oxidizing atmosphere by addition of a metal chelate derived by reacting a metal or a metal oxide or carbonate with a compound <FORM:0630319/IV (a)/1> where X is a hydrocarbon, alkoxy or hydrocarbon substituted amino radical, and Y is oxygen or a substituted imino radical, and the substituted imino radical is present only when X is hydrocarbon. Metal chelates mentioned are chromium acetylacetonate; copper N.N1-ethylenimine-bis-acetylacetonate; copper ethylacetoacetate; chromium ethylacetoacetate.  Compounds from acetoacetanilide or acetoaceto-toluidine are also mentioned. Many metals are mentioned as having been found suitable.  The proportion of metal chelate may vary from .01-10 per cent.  The metal chelate and silicone may be mixed in a common solvent, e.g. toluene, or the metal compound may be dissolved directly in a fluid silicone.  The mixture may be heated to 200-250 DEG  C.  The metal chelates do not inhibit polymerization of an unsaturated silicone, as is illustrated by an example in which a solution in a volatile solvent of a copolymer from 10 per cent allyl methyl silicon diethoxide and 90 per cent dimethyl silicon diethoxide was mixed with copper ethyl acetoacetate and benzoyl peroxide and polymerized by heat on a sheet material.  Sheet electrical insulation may be prepared by bonding a plurality of sheets of asbestos cloth or glass fibre cloth impregnated with a silicone containing a metal chelate (see Group VIII).  Similarly a silicone composition with a metal chelate may be applied to a wire as insulation.  Mica dust may be included in the composition, or mica flakes may be bonded with them to form sheets from which electrical insulation may be made. Fluid polymers stabilized with the metal chelates may be used in transformers (see Group XXXV) capacitors or in cables with fluid insulation.

As shown, by pressing on the base 12 of the device, a spring rod 16 pushes the toothed piston-rod .  5 so that the piston 4 moves to eject medicament through the outlet nozzles 3, there being a spring 11 which biases the base 12 and moves the spring rod onto the next tooth after each application. The piston rod 5 is guided in a sleeve member 7, and a cover member 15 may be removed so that, after lifting out the parts 7, 12, the device may be charged with medicament. A coloured pin 18 on the piston 4 projects through an aperture in the device (as shown) to indicate that the device is empty. In an alternative device (Figure 2, not shown), the spring rod 16 is moved by finger pressure on a diaphragm (26) at the base of the device, and a transparent section 1(28) and indicator marks (30, 32) allow the amount of medicament in the device to be determined. The alternative device may be opened into two halves (1', 21) to facilitate filling. Abutments may be provided on the inside of the device to adjustably limit the movement of the member 12 and so vary the stroke of the dispensing piston. The device is said to be suitable for introducing a medicament into a body cavity, for dispensing a cosmetic, or for inserting a contraceptive paste into the vagina.
